Theoretical errors significantly impact measurement accuracy.
Combining linear collider and LHC data improves overall Higgs coupling constraints.
Abstract
Higgs couplings can be measured at a linear collider with high precision. We estimate the uncertainties of such measurements, including theoretical errors. Based on these results we show an extrapolation for a combined analysis at a linear collider and a high-luminosity LHC.
